Thorikos

For lunch we stopped at Thorikos, a site in Attica that was in use for a long time and for many purposes. Mostly, it is famous for the theater that is there- it's a very old theater, and interesting for several reasons that I will point out in a sec- and for mining equipment- this is, after all, in the region of the Laurion silver mines that were so important in Athenian history. So, this is the theater. Most of the theaters that you can think of from the ancient world- the theater of Dionysus in Athens, or the theater at Epidauros- are round in shape. However, theaters weren't always round, and this one at Thorikos is proof of that.
Now, it may look a bit round, when you only look at the edges. However...

When you look only at the middle, there's no curvature at all. How is that?
That's how- the middle of the theater actually is straight, and there are essentially corners where the theater curves around the orchestra. Once upon a time, most theaters were probably a lot more square than their classical counterparts. This is sort of a transitional phase.

At Thorikos there is also some ancient mining equipment, which I saw and did not photograph, and some Mycenaean burials, which are up on the acropolis which we didn't see.
